IMPROVEMENT IN HOOP-LOCKS FOR SECURING THE ENDS 0F METALLIC BANDS.

Specification forming part of Letters Patent No. 23,249, dated March l5, 1859.

To all whom it may concern.-

Be it known that I, I. C. INGERsoLL, of Green Point, in the county of Kings and State of New York, have invented a new and lmproved Hoop-Lock for Securing Together the Ends of Metal Bale-Hoops; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this description, in which- Figurel is a longitudinal section of my invention, taken in the line x x, Fig. 3; Fig. 2, a transverse section of the same, taken in the line x Fig. l; Fig. 3, an outer face view of the same; Fig. 4, an inner face view of the same; Fig. 5, an edge or side view ofthe same.

Similar letters of reference indicate corresponding parts in the several gures.

This invention consists in the employment or use of a metal loop in onnection with a metal key, so arranged or Iormed and tted within the loop as to securely lock, when properly adjusted, the ends ofthe hoop in the loop, as hereinafter fully shown and described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a metal loop,whicli may be of ordinary gray or cast iron. This loop may be described asbeing composed of the side pieces a n, connected by end pieces,b b', one end piece, b,being near theinner, and the outer end piece, b', near the outer side of the loop, as shown Clearly in Fig. l.

B represents what l term the key/ which is also of ordinary gray or other cast iron, and of bent form, it having two plates, c c', connected by an oblique or central portioind, as shown clearly in Fig. l.. The key B, when fitted in the loop A, has one plate, c, fitting against the outer side of the end piece b, and the other plate, c, fitting against the inner side of the end piece b, as shown clearly in Fig. 1, t-he oblique central portion, d, compensating for the relative position of the end pieces, b b', of the loop.

At the outer end of the plate c of the key B there are two hook-shaped projections, e e,

one at each side, and these projections, when l the key is in the loop, t over oblique or beveled ends f ofthe sides a a ofthe loop,as shown clearly in Fig. 5. The outer end of the plate c also expands laterally, so as to form a sort of dovetail lock between the inner surfaces of the sides a a ofthe loop, as shown clearly at cX in Fig. 4.

The loop A and key B form the hoop-lock, and it is used or applied as follows: The iron hoops are adjusted in the box of the press, as usual, and when the material is compressed the ends of the hoops are fastened in the loops A. The end g of a hoop, for instance, is bent around the end piece b of the loop, as shown clearly Ain red, Fig. 1, and the opposite end,h, is bent around the end piece b. The key B is the'key bearing against the end of the loop at the inner side of the end piece b', and the plate c bearing against the end b on the end h of the hook, the hooks e e of the plate b being fitted over the oblique ends f of the sides a a ofthe loop, and the outer end of plate c fitted between the outer oblique portions of the sides a a. The end h ofthe hoop is then bent around and over the outer side of plate o, and passed a g of the hoop around the end piece b', as shown in red, Fig. l.

From the above description it will be seen that a very simple and efficient hoop -lock is obtained. It may be very readily applied, and the key is prevented from being casually loosened in consequence of the hook-shaped projections e e fitting over the oblique ends f of the sides a a of the loop, and the expanded outer end, c', of the key B fitting between the opposite dovetail ends of the sides c a, the

. strain or pull of the hoop, as well as the bent end h of the hoop, favoring the keeping or securing of the key in proper place or position. The outer surface of the plate c of the key B has ledges t t', one at each side, as shown more particularly in Figs. 2 and 3, in order to prevent the end h of the hoop from slipping laterally off the plates c.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The loop A and key B, tted together and applied to the hoop, substantially as and for` 1 the purpose set forth.
